|
|
|
- If an item has been sent by the comment author to the top-level post owner to relay on |
|
to the rest of the contacts on the top-level post, the top-level post owner should check |
|
the author_signature, then create a parent_author_signature before relaying the comment on |
|
- If an item has been relayed on by the top-level post owner, the contacts who receive it |
|
check only the parent_author_signature. Basically, they trust that the top-level post |
|
owner has already verified the authenticity of anything he/she sends out |
|
- In either case, the signature that get checked is the signature created by the person |
|
who sent the salmon |
